应用罗克休充填技术治理采煤工作面顶板局部冒落

Application of Rockxiu foam stowing technology to control local roof cavings in coal face

应用罗克休材料充填采煤工作面冒顶区,提高冒顶区围岩的稳定,并防止冒落区的进一步扩大和有害气体的积聚。介绍了充填方案的设计、施工及应用效果。

The application of Rockxiu foam material in filling the roof cavity after caving occurs in the roof of coal faces.This can improve the stability of the surrounding rock of the face roof caving zones,prevent the expansion of roof caving zones in coal faces and prevent the accumulation of harmful gases in and around the face caving zones.In this paper,design of the stowing or filling plan is introduced as well as the application effects of this technology.
